摘要

目的：探讨非功能性胰腺内分泌肿瘤的DCE MR表现及诊断价值。方法：对13例经病理证实的非功能性胰腺内分泌肿瘤的DCE MR及临床资料进行回顾性分析。结果：肿瘤7例为实性，6例为囊实性。最大直径28～122 mm，平均74 mm。MR平扫肿瘤呈T1WI等或稍低信号，T2WI为稍高或高信号，囊变区为高信号。动态增强多数肿瘤呈较明显持续强化，囊性成分未见强化。12例肿瘤边缘见较完整或不完整包膜，多呈较低信号，增强呈较明显延迟强化。2例见胆总管及主胰管增宽；4例见肝脏转移，1例见腹膜后淋巴结转移，2例肿瘤周边广泛侵犯。结论：非功能性胰腺内分泌肿瘤以单发较大肿块常见，边界较清晰，MR对其诊断有较大价值。

Abstract

Objective: To investigate the appearances and diagnostic value of dynamic contrast enhanced(DCE) MR for nonfunctioning pancreatic endocrine tumors. Methods: DCE MR in 13 cases and clinical data which were proved to be nonfunctioning pancreatic endocrine tumor by pathology were analyzed retrospectively. Results: There were 7 solid tumors and 6 solid-cystic tumors, the maximum diameter was 28~122 mm, the average diameter was 74 mm. All tumors MR T1WI showed equal or low signal and T2WI showed high signal on non-contrast scan. On dynamic contrast enhanced scan, most tumors showed obvious continued enhancement, the cystic area without enhancement. Envelope can be seen in the edge of 12 cases, showed low signal on non-contrast scan and obvious delayed enhancement on dynamic contrast enhanced scan. Conclusions: Central tumors always showed single large mass and with clear boundary, DCE MR is useful for the diagnosis.
